Description

Technical Field

[0001] This utility model relates to the field of material handling and conveying technology, and in particular to a top-bottom reversing device. Background Technology

[0002] In the fields of food processing and packaging production, it is often necessary to flip materials with specific shapes (such as instant noodle buckets with extended rims on top, packaging boxes, etc.) up and down to meet the needs of subsequent processing, labeling, or testing.

[0003] Existing top-and-bottom reversing equipment typically requires vertical height adjustment of the metal wire used to drive the material's rotation when handling materials of varying heights. However, during adjustment, the relative position of the wire's installation location and the spring's connection point changes, often resulting in variations in spring tension. After adjusting the wire height, operators must repeatedly readjust the spring tension to ensure it provides the appropriate force for material rotation. This not only increases operational steps and prolongs equipment adjustment time, impacting production efficiency, but also makes it difficult to maintain consistent spring tension during multiple adjustments. This can lead to deviations in rotation force for different materials, affecting the stability of the rotation effect and potentially causing material damage or rotation failure due to improper force, resulting in production inconvenience.

[0004] Therefore, a top and bottom reversing device was designed. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a top and bottom reversing device. It solves the problem that when adjusting the vertical height of the metal wire in existing top and bottom reversing devices, the spring tension changes due to the change in the relative position of the connection point between the metal wire and the spring, requiring multiple adjustments to the spring tension.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A material reversing device includes a conveying device body, a material reversing component for flipping materials fixedly mounted on the outer wall of the conveying device body by bolts, a movable bar slidably mounted on the top of the material reversing component, a rotating rod rotatably mounted on the top of the rotating rod, and a metal wire movably mounted on the outer wall of the rotating rod. The metal wire drives the material to flip by contacting and abutting against the material. The metal wire and the movable bar are elastically connected by a spring for resetting the metal wire.

[0008] Preferably, the upper and lower reversing components include a mounting plate, the top of which is provided with a sliding groove, and the bottom of the moving strip is fixedly installed with a protrusion, the protrusion being adapted to and slidably connected to the sliding groove.

[0009] Preferably, an adjustment groove is provided on the outer wall of the movable strip. The adjustment groove is strip-shaped, and an adjustment block is provided on one side of the adjustment groove. The adjustment block is fixed to the movable strip by bolts, which pass through the adjustment groove. An arc-shaped block is provided on the top of the adjustment block, and the adjustment block can be adjusted to a fixed position along the length of the adjustment groove.

[0010] Preferably, a toothed groove is provided on one side of the moving bar, the toothed groove is located on the side near the rotating rod, and the toothed groove is continuously arranged along the length direction of the moving bar.

[0011] Preferably, a knob and a gear are fixedly fitted on the outer wall of the rotating rod from top to bottom, and the gear meshes with the tooth groove.

[0012] Preferably, the top outer wall of the rotating rod is threaded, and a moving block is threaded onto the outer wall of the thread.

[0013] Preferably, a limiting slide bar is fixedly installed on the top of the mounting plate, and the limiting slide bar passes through the moving block and is slidably connected to the moving block.

[0014] Preferably, a limiting plate is fixedly installed on the top of the limiting slide rod, and the limiting plate is rotatably connected to the rotating rod.

[0015] Preferably, the metal wire is designed with multiple bends, and its bottom is concave to match the shape of the material. One end is designed with a hook shape, and the middle of the metal wire passes through the moving block and is movably connected to the moving block.

[0016] Preferably, one end of the spring is designed as a loop to be adapted and connected to the hook-shaped part of the metal wire, and the other end of the spring is designed as a hook to be adapted and connected to the arc-shaped block on the top of the adjusting block.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention, by incorporating upper and lower return components, maintains constant spring tension during vertical height adjustment of the metal wire through a linkage structure. Rotating the knob drives the rotating rod to rotate, which in turn, on one hand, drives the metal wire to adjust its vertical height through the engagement of a threaded mechanism with a moving block; on the other hand, through the meshing of a gear with the toothed groove of a moving bar, it drives the protrusion at the bottom of the moving bar to move horizontally synchronously within the groove. This synchronous adjustment in both vertical and horizontal directions ensures a stable relative position between the metal wire and the adjusting block, thereby guaranteeing that the spring connecting them is always at the preset tension. This eliminates the need to readjust the spring tension after adjusting the metal wire height, simplifying the operation process, ensuring consistent material turning force, and improving adjustment efficiency and turning stability.

Example

[0030] Please see Figure 1-5A material reversing device includes a conveying device body 1, a material reversing component 2 fixedly mounted on the outer wall of the conveying device body 1 by bolts for flipping materials, a movable bar 3 slidably mounted on the top of the material reversing component 2, a rotating rod 4 rotatably mounted on the top of the rotating rod 4, and a metal wire 6 movably mounted on the outer wall of the rotating rod 4. The metal wire 6 drives the material to flip by contacting and abutting against it. The metal wire 6 and the movable bar 3 are elastically connected by a spring 5 for resetting the metal wire 6. The material reversing component 2 includes two mounting plates 2. 1. One of the mounting plates 21 has a groove 211 on its top, and a protrusion 32 is fixedly installed on the bottom of the moving strip 3. The protrusion 32 is adapted to and slidably connected to the groove 211. An adjustment groove 31 is provided on the outer wall of the moving strip 3. The adjustment groove 31 is strip-shaped, and an adjustment block 34 is provided on one side of the adjustment groove 31. The adjustment block 34 is fixed to the moving strip 3 by bolts, which pass through the adjustment groove 31. An arc-shaped block is provided on the top of the adjustment block 34, and the adjustment block 34 can be adjusted and fixed along the length of the adjustment groove 31. A toothed groove 33 is provided on one side, located near the rotating rod 4, and is continuously arranged along the length of the moving bar 3; a knob 42 and a gear 44 are fixedly fitted on the outer wall of the rotating rod 4 from top to bottom, and the gear 44 meshes with the toothed groove 33; a thread 41 is provided on the top outer wall of the rotating rod 4, and a moving block 411 is threadedly fitted on the outer wall of the thread 41; limit slide rods 22 are fixedly installed on the top of the two mounting plates 21 respectively, and the two limit slide rods 22 pass through the corresponding moving blocks 411 and are connected to the corresponding moving blocks. 411 Sliding connection; Limiting plate 43 is fixedly installed on the top of limiting slide rod 22, and limiting plate 43 is rotatably connected to rotating rod 4; Metal wire 6 is designed with multi-angle bending, and its bottom is concave to match the shape of the material. One end is designed with a hook shape. The middle of metal wire 6 passes through moving block 411 and is movably connected to moving block 411; One end of spring 5 is designed with a loop shape to adapt and connect with the hook shape of metal wire 6, and the other end of spring 5 is designed with a hook shape to adapt and connect with the arc-shaped block on the top of adjusting block 34.

[0031] The upper and lower reversing components 2 are fixedly connected to the conveying device body 1 by bolts, making the installation process simple;

[0032] The moving bar 3 is slidably connected to the slide groove 211 of the mounting plate 21 via the bottom protrusion 32. With the meshing transmission of the gear 44 on the rotating rod 4 and the tooth groove 33 of the moving bar 3, the horizontal movement of the moving bar 3 is stable. At the same time, the thread 41 at the top of the rotating rod 4 is threadedly connected to the moving block 411. The vertical height of the moving block 411 can be precisely adjusted by rotating the knob 42, thereby adjusting the position of the metal wire 6. It can easily adapt to materials of different heights. The adjusting block 34 can be adjusted along the adjusting groove 31 of the moving bar 3 to achieve flexible adjustment of the tension of the spring 5, meet the flipping requirements of materials of different weights and hardness, and improve the equipment's adaptability to diverse materials.

[0033] The meshing transmission between gear 44 and tooth groove 33 ensures the synchronization of the horizontal movement of moving bar 3 with the rotation of rotating rod 4. Limiting slide rod 22 passes through moving block 411 and slides with it, playing a guiding and limiting role in the vertical movement of moving block 411, effectively preventing moving block 411 from rotating or shaking during movement, and ensuring the stability of vertical height adjustment of metal wire 6. Limiting plate 43 can limit the maximum movement stroke of moving block 411 and prevent it from disengaging from rotating rod 4.

[0034] The multi-angle bending design of the metal wire 6, with its concave bottom, allows it to closely conform to the shape of the material, increasing the contact area and enabling more stable material driving during the flipping process, preventing material slippage or insufficient flipping angle. The metal wire 6 passes through and is movably connected to the moving block 411 in the middle, ensuring that the metal wire 6 can adjust its position synchronously with the moving block 411, while also providing a certain amount of room for movement when in contact with the material, reducing rigid impact on the material. The special design at both ends of the spring 5 allows it to be adapted and connected to the hook of the metal wire 6 and the arc-shaped block of the adjusting block 34, respectively, ensuring a firm connection and easy disassembly and replacement. At the same time, the elasticity of the spring 5 can promptly drive the metal wire 6 to reset after the material is flipped, ensuring the smooth progress of the next flipping operation.

[0035] The length and tension of the spring, i.e. the elastic force, must be matched with the weight of the instant noodles. The maximum deformation elastic force of the spring 5 must be slightly greater than the weight of the instant noodles to ensure that the metal wire 6 can reliably push the material to flip, while avoiding excessive elastic force that could cause the material to deform or flip excessively.

[0036] Instant noodle weight parameters

[0037] A typical cup of instant noodles, including the noodles, seasoning packet, and the cup itself, weighs approximately 80-150g. If only the noodles themselves are included, excluding the packaging, the weight is approximately 50-100g. The following calculations are based on an example of 80g (0.08kg).

[0038] Spring force formula: F = kx, where F is the elastic force, k is the spring constant, and x is the deformation.

[0039] The following conditions must be met: F ≥ G = mg, where G is the weight of the instant noodles, m is the mass, and g is taken as 9.8 N / kg.

[0040] Substituting the data: F ≥ 0.08 kg × 9.8 N / kg = 0.784 N

[0041] When the free length is not under force

[0042] Based on the equipment structure, the free length of the spring must meet the following requirements: after assembly, there should be no slack in the connection with the metal wire 6 and the adjusting block 34, meaning it should be under slight force in its natural state; during maximum deformation, the instantaneous material flipping should not exceed the elastic limit of the spring 5. Referring to the equipment dimensions, a free length of 8-15cm is recommended. If the vertical adjustment range of the upper and lower material reversing components is 5-10cm, a spring free length of 10cm is preferable, avoiding both excessively short lengths that would cause assembly difficulties and excessively long lengths that would result in insufficient deformation.

[0043] When the instant noodles come into contact with the metal wire 6 and push the spring 5 to deform, the deformation x is recommended to be 10%-20% of the free length, i.e., 1-3cm. At this time, the working length of the spring is: 10cm−1cm=9cm. The minimum working length is 10cm−3cm=7cm, ensuring that the elastic force is within the range of 0.784N-2.35N and the spring constant is 0.8N / cm.

[0044] The tension is determined by the spring constant k. The larger the k is, the "stiffer" the spring is and the greater the elastic force under the same deformation.

[0045] For 80g of instant noodles:

[0046] Stiffness coefficient: k = 0.5 − 1.0 N / cm. If k = 0.8 N / cm, then the deformation x ≥ 0.784 N ÷ 0.8 N / cm ≈ 0.98 cm (approximately 1 cm), which meets the above deformation range.

[0047] If the weight of the instant noodles increases by 150g, you can choose k=1.0−1.5N / cm to ensure that the elasticity is improved accordingly.

[0048] Workflow

[0049] First, the two mounting plates 21 of the upper and lower reversing components 2 are fixedly installed on both sides of the conveying device body 1 with bolts to ensure that the installation is firm and stable, providing a solid foundation for the subsequent operation of the equipment; then, the two ends of the spring 5 are hung on the hook of the metal wire 6 and the arc-shaped block on the top of the adjusting block 34 respectively to complete the connection of the spring 5.

[0050] To adjust the height of the material to be flipped as needed, the vertical height of the wire 6 needs to be adjusted. The specific operation is as follows: Rotate the knob 42 to drive the rotating rod 4 to rotate. When the rotating rod 4 rotates, it will simultaneously drive the gear 44 to rotate. Since the moving block 411 is threadedly connected to the thread 41 at the top of the rotating rod 4, the rotation of the rotating rod 4 can drive the moving block 411 to move vertically along the axis of the rotating rod 4, thereby driving the wire 6 to adjust its vertical height. At the same time, the gear 44 meshes with the tooth groove 33 on one side of the moving bar 3, which will drive the moving bar 3 to drive the bottom protrusion 32 to move synchronously in the horizontal direction within the slide groove 211. This ensures that the tension of the spring 5 remains basically unchanged when the upper and lower material reversing parts 2 are adjusted in height, thus ensuring the stability of the equipment adjustment process.

[0051] If the spring force of spring 5 needs to be adjusted to accommodate materials of different weights and hardnesses, the nut fixing the adjusting block 34 can be loosened to allow the adjusting block 34 and bolt to slide in the adjusting groove 31; after adjusting to the appropriate position, the nut can be tightened to fix the adjusting block 34, thus completing the adjustment of the spring force of spring 5.

[0052] To ensure that the moving blocks 411 on both sides move to the same height, two methods can be used: one is to measure the adjusted height with a ruler; the other is to rotate the knob 42 so that both sides rotate the same number of times to ensure that the moving height of the moving blocks 411 on both sides is approximately the same, thus ensuring the consistency of the operation of both sides of the equipment.

[0053] After the conveyor body 1 is started, for materials that are similar to the shape of instant noodles with a portion of the top extending outwards, the material with the protruding eaves facing upwards in the initial state will come into contact with the concave part at the bottom of the metal wire 6 when the material is conveyed on the conveyor body 1 to the vicinity of the upper and lower anti-material components 2. Under the continuous drive of the conveyor body 1, the material moves continuously, and through the limiting effect of the metal wire 6, the material will be flipped, realizing the upside down, and finally the protruding eaves of the material will face downwards.

[0054] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
